Figure 9-5 User authorize to FlashCopy 45 TB of data with a license scope of ALL

For PTC and RMC, you may have FB data for open systems only, or you may have CKD for zSeries only, or you may have both FB and CKD data. For RMC, you will need the license feature for both the primary storage unit and the secondary storage unit.

Figure 9-6 on page 173 shows an example of a Metro Mirror configuration. In this case, the user has to purchase Remote Mirror and Copy function authorization for 45 TB with Metro Mirror feature for both the primary DS8000 and secondary DS8000.
